5	select VHOST
6	---help---
7	  This kernel module can be loaded in host kernel to accelerate
8	  guest networking with virtio_net. Not to be confused with virtio_net
9	  module itself which needs to be loaded in guest kernel.
10
11	  To compile this driver as a module, choose M here: the module will
12	  be called vhost_net.

16	depends on TARGET_CORE && EVENTFD
17	select VHOST

20	Say M here to enable the vhost_scsi TCM fabric module
21	for use with virtio-scsi guests

23config VHOST_VSOCK
24	tristate "vhost virtio-vsock driver"
25	depends on VSOCKETS && EVENTFD

27	select VHOST
28	default n
29	---help---
30	This kernel module can be loaded in the host kernel to provide AF_VSOCK
31	sockets for communicating with guests.  The guests must have the
32	virtio_transport.ko driver loaded to use the virtio-vsock device.
33
34	To compile this driver as a module, choose M here: the module will be called
35	vhost_vsock.

37config VHOST
38	tristate
39	---help---
40	  This option is selected by any driver which needs to access
41	  the core of vhost.
42
43config VHOST_CROSS_ENDIAN_LEGACY
44	bool "Cross-endian support for vhost"
45	default n
46	---help---
47	  This option allows vhost to support guests with a different byte
48	  ordering from host while using legacy virtio.
49
50	  Userspace programs can control the feature using the
51	  VHOST_SET_VRING_ENDIAN and VHOST_GET_VRING_ENDIAN ioctls.
52
53	  This is only useful on a few platforms (ppc64 and arm64). Since it
54	  adds some overhead, it is disabled by default.
55
56	  If unsure, say "N".
